o6asan's soliloquy.

   Actually, Cygwin has libev and nghttp2 packages now. So, you can use h2load feature even if you don’t build nghttp2 by yourself. Nevertheless, if you build nghttp2 on Cygwin, you need to build the Jansson and the spdylay before building it because Cygwin doesn’t have their packages. But, according to the current trend, I think you don’t need the spdylay package. (2016.6.18)

   Now, I have two zip files. One is H2LOAD_dll_package_x86.zip, another is H2LOAD_dll_package_x64.zip. If you download one of them, you can do the test by h2load on your Windows PC. Run cmd.exe and do like this.
> h2load -n100000 -c100 -m10 https://localhost
   If you do this test, you should create your own local server. Because the test might be a cyber attack for the server if you set numbers too high as values of -n -c -m. Be careful.
   I wrote like this before:‘I don’t know why, but it looks like telling Apache without HTTP/2 is faster. Gee!’. This time, I had interesting results. See HTTPS with HTTP/2 and HTTPS without HTTP/2. The test tells that the server supports HTTP/2 is good at dealing with concurrent streams than the server doesn’t support HTTP/2. This is one of HTTP/2 features.

   I’ll write about my hard work to get these files (^_^;).
   [Caution]: The steps blow give the files contained by H2LOAD_dll_package_x64.zip. If you want to have the files for x86 PC, you have to do all steps by setup-x86.exe on a Windows x86 PC.

   Continued from this post. As I finished preparing for supporting HTTP/2, I re-edited my httpd.conf and httpd-ssl.conf.
 
   On the httpd.conf, I un-commented the next line.
　　　　　LoadModule http2_module modules/mod_http2.so
   On the httpd-ssl.conf, I added the next line just after <VirtualHost o6asan.com:443>.
　　　　　Protocols h2 http/1.1
   h2 is HTTP/2 with TLS and h2c is HTTP/2 without TLS. I don’t use h2c on the server.
 
   Reboot Apache to enable Http/2. That’s it.

   They released Apache 2.4.17 on Oct 13 and Steffen released the same version at ApacheLounge on Oct 12. The version has mod_http2 for its core module and Steffen’s version was built with nghttp2 v1.3.4. See ChangeLog. So, I can test HTTP/2 on my server now. Yes! Just test. Because they say “This module is experimental.”
